I replied to 1998silverbird's comments in another thread, thought I'd cross-reference what I consider drone verses thrumming. The L76 engine has some terrible harmonics, but only you can decide what is right for your needs.

I understand what you mean by your definition of "drone", but to me the V4 "tuba sound" is still drone, it's just in a lower frequency band. The "gurgly" sound in V4 mode is a set of frequencies (varying somewhat) that goes on and on; that, to me, is the definition of drone.

I just finished my first day of Solo Axlebacks and from my past experience with drone on my old BMW 540 with custom exhaust, I can say this does not drone at all. The afm sound is noticeable but not a drone and it doesn't bother me..... in fact I was actually trying to keep it going to see if it got annoying and it didn't. I'm in love with my new Solo axle back! I finally have that muscle car sound that this car deserves.

I've had my Solo axlebacks on for 500 miles now. The only other modification to the exhaust system is a X pipe where the mid-muffler used to be.

After I first installed them, there was no drone but a noticeable change in the exhaust note when DOD kicked in on the highway. I left the J-pipes the way they were setup from Solo and thought I would wait and see how it sounded after the break in period.

After 500 miles, the exhaust sounds even better/louder and the DOD kick over is almost non-existent now. It’s great driving in a downtown location with your windows down and hearing the V8 exhaust note echo off the buildings around you. I even let my buddy drive by in my car so I hear it firsthand outside of the car. Truly a perfect setup for the G8.

For those who think there's cabin drone with Solo axlebacks need to try the "washer mod" or some Magnaflows. Those are the definition of drone. Solo's, with some break in time and maybe a little adjustment of the J pipes, are much quieter in the cabin.

First, let me say I love my solo axleback. It sounds great and the quality/fit is top notch. And it doesn't drone in v8 mode whatsoever at highway speeds. Job well done solo.

However, I'll reiterate another point of view I've shared on this board regarding the AFM mode tone - it absolutely stinks. And that's fine - it's not designed to cancel out those awful tones. But I am telling you it's not good and I would 100% completely call it a "drone". You are going to hear it at highway speeds and it's not pleasant. You'll also hear AFM flickering on and off especially often when tooling around town in the 30-45 mph range.

I initially had straight pipes /muffler delete from PM of FL and the exhaust tone in v8 mode sounded about the same (good) as the solo axleback, except it droned. The AFM mode for both exhausts sounded the same to me - both equally awful.

I tried to convince myself that it wasn't bad until I had to live with it all winter....not good. I grew weary of it and bought a AFM-delete tune from VMS. Took care of the afm tone issues.

The Solo 100% cured the highway 2400-2900 rpm drone zone issues for me. Again, great product, but I wouldn't want anyone thinking the afm mode is "fine" and "liveable" for everyone. I just can't agree with that statement but I respect if anyone else has a different view.

T409 stainless will develop surface rust in a more harsh climate, but that will not effect the longevity or performance of the product. The tips are T304 polished stainless, so they will stay shiny as long as you clean them. Thanks.

Guys,
I ordered a Mach balanced from a supporting vendor and I was sent the Mach shorty balanced. How much louder is the Mach shorty balanced over the Mach balanced? I'm wanting more flow but not a super loud exhaust. I do family road trips and wanted the Mach balanced for the quieter...
